Due to the introduction of an aFRR market (secondary control reserve), Svenska kraftnät requires a load frequency controller to ensure system balancing for each of Svenska krafnät's total of four bidding zones. A real-time interface will be established between the LFC and ENTSO-E with PICASSO (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation), also implemented by PSI, to activate control power from a Europe-wide common merit order list.
In addition, an HVDC control module will be implemented as an option in order to flexibly use HVDC connections in the future, especially for system services. This is particularly essential considering that HVDC systems play a central role in reliable power transmission over long distances from the point of generation to the consumer.
The project will be managed in close cooperation with the Swedish subsidiary PSI Scandinavia in Karlstad. The overall project, including implementation and activation in Sweden, is scheduled for 12 months.
Svenska kraftnät operates the Swedish high-voltage transmission grid for electricity. With this order PSI wins an important new customer in Scandinavia in the area of transmission grid.
